The Centre for Experimental Social Sciences (CESS) is an inter-disciplinary research Centre at Oxford University engaged in laboratory experimental work in the social sciences. The research tools used in the Centre are laboratory and online experiments in which paid human subjects engage in decision-making tasks. For our online experiments, participants are invited to visit a webpage and answer some surveys, while for our laboratory experiments, participants come to our laboratory.

On this site you can register to participate in experiments. Participants in experiments receive payment for their time and effort. In addition, as the results from these experiments are used for scientific publications, your participation helps research in the University of Oxford.
